Abstract

Software-defined radios allow flexible implementation of different basebands in digital signal processors. For communications transceivers this introduces an engineering problem: how to manage the different protocol stacks that may be required to work above the baseband software. To solve this, we propose a consistent software architectural framework for the dynamic implementation of these different protocols within an embedded environment. We discuss its requirements and present one possible approach based on STREAMS
